STONE-CRUSHER.

Specification of Letters Patent.

Original application led February 26, 1904, Serial No. 195,459. Divided and this application filed May 13, 1907. SeriallNo. 373,239.

To all 'whom t may concern:

Be it known that I, EDGAR B. SYMoNs, a citizen of the United States, residing at l\liluaukee` in the county of Milwaukee and Stateof IVisConsin, have invented a certain new and useful Improvement in Stone- Crushers, of which the following is a specification.

My invention relates to stone Crushers and is illustrated in the accompanying drawings whereinl Figure 1 is a vertical section, Fig. 2 a horizontal section on the line 2--2 of Fig.v1,

and Figs. 3, 4, 5 and 6 details ofthe two inner cases.

Like parts are indicated by the same letter in all the figures. 'p

A is the hopper resting on the base B and surmounted by the spider crown C.

D is a tie-rod which locks the parts together.

E is an inner hollow rotary crusher head mounted about the tie-rod and-supported on a plate F, the lower rim G of which incloses a ange H on the base. v

I is an outer roller bearing cage having the rollers J, and K in an inner roller bearing cage having the rollers L. Between these two sets ofl rollers is mounted the eccentric sleeve M which rests at'i'ts lower edge on the bevel gear 'N which is driven bythe pinion O on the shaftP, which in turn is driven from the pulley Q.. l

R is a protected cavity in the base in which the pinion O rotates. The cage K rests on the collar S and the cage I on the support F. 'The roller bearing cages consist of perforated rings with connecting bars and i11- termediate rollers. I have not shown'all of the parts including the support and driving mechanism vbecause it seems unnecessary as thisparticular invention has reference only to the use of the 'eccentric sleeve. f

The use and operation of my invention are as follows: Power being applied, the shaft Protates and causes the eccentric sleeve to rotate around thev fixed 'center shaft or tierod. This sleeve rotates between the two sets of rollers and causes the crusher head E to oscillate within the hopper, the stone being fed through the upper spider crown,

falls in between the two Crusher plates and as the head oscillates is crushed and broken,

the small particles falling out between the arms of .the base.

This application is a divisional application of my originall application tiled February Qth, 1904, No. 195,459, and embraces one of the species there presented which could not be claimed in that application, but which are described in the application and illustrated particularly in connection with Figs. 9 to 14 inclusive. The broad claims and claims on the other species are retained in the original application.

I claim:

1. In a crushing machine, the combination of an outer crushing shell having a spider arm bottom and a removable crown piece, a centrally located tie-shaft fixed to said bottom and crown piece, a Crusher head movable on the shaft and containing a rotating eccentric sleeve and means for rotating said sleeve.

2. In a crushing machine, the combination of an outer crushing shell with a crown piece fitted to said shell, a centrally located fixed shaft supported within such shell by bearings in the crown piece and in the shell, a collar of rollers within the crushing shell surrounding said shaft as a roller bearing, and an eccentric sleeve surrounding said rollers and means for rotating. said sleeve.

3;. In a crushing machine, the combination of a stationary crushing shell with a centrally located stationary shaft supported by suitable connections to said shell, a roller collar surrounding said shaft and comprising a series of rollers, an eccentric sleeve within the crushing shell surrounding said roller collar, and means for turning said sleeve. l

5. In a crushing machine, the combination of a stationary outer crushing shell with a centrally located and substantially vertical stationary shaft held by connections to said shell, an eccentric sleeve within the crushing shell mounted on a roller bearing around said shaft, acrushing head mounted on a roller bearing surrounding said sleeve, and means for turning said sleeve.

6. In a crushing machine, the combination of a-n outer crushing shell having radial armed end pieces with a centrally located shaft supported by said end pieces, a roller collar surrounding said shaft, an eccentric sleeve surrounding s aid roller collar, a

roller collar s urrounding said sleeve, a

crushing head surrounding said second collar, and means for turning said sleeve.

7. In a crushing machine, the combination of a hollow crusher head with a cylindrical device adapted to rotate eccentrically therein so as to impart an oscillating movement thereto, lsuch device com rising two independent members one wit in the other, one of which consists of a roller collar, the other of an eccentric sleeve, and means for imparting rotary motion to the sleeve.

8. In a crushing machine, the combination of a stationary shaft, a hollow crusher head surrounding said shaft, and three rotatable devices within each other and all interposed between the shaft and-such crusher head, the intermediate device being an eccentric sleeve, and the inner and outer of such devices comprising a plurality of rollers, and rotating means associated with the middle device so as to 'oscillate the crusher.

9. In 'a crushing machine, the combination of a hollow crusher head having an exterior crushing surface with a stationary crushing member, a stationary shaft and a cylindrical device mounted eccentrically on said shaft and located within said crushing surface to impart an oscillating movement to the head, said cylindrical device consisting of an eccentric sleeve.

10. In a crushing machine, the combination with a stationary device of two crushing bodies having opposed crushing surfaces, one of said bodies being movable, and oscillating means interposed between the stationary device and the movable crushing element for giving the latter an oscillating movement with respect to the former, substantially equal at all points therealong, said means containing anl eccentric sleeve.

11. In a crushing machine, the combinal tion with a stationary device of two crushing bod1es having opposed crushing` surfaces, one of said bodies being movable, and an eccert-ri(` device internosei between the stationary device and the movable crushing element for giving the latter an oscillating movement with respect to he former. said eccentric device 'containing an eccentric leve located within the movable crushing 12.
